Identification devices

Abstract

Described examples relate to a radio frequency identification (RFID) device configured to be coupled to a surface of an object. The RFID device may include a housing having a first casing and a second casing. The RFID device may also include an RFID tag disposed between the first casing and the second casing. The RFID tag may comprises an antenna and an integrated circuit coupled to the antenna. Further, the RFID device may include a first break-line defined in the first casing and extending between an inner edge and an outer edge of the first casing. The first casing may be breakable along the first break-line. In addition, the RFID device may include a second break-line defined in the second casing and extending between an inner edge and an outer edge of the second casing. The second casing may be breakable along the second break-line.

What is claimed is:

 an RFID tag disposed between the first casing and the second casing, the RFID tag comprising an antenna and an integrated circuit coupled to the antenna; 
 a first break-line defined in the first casing and extending between the inner edge and the outer edge of the first casing, the first casing being breakable along the first break-line; and 
 a second break-line defined in the second casing and extending between the inner edge and the outer edge of the second casing, the second casing being breakable along the second break-line. 
 
     
     
       2. The RFID device of  claim 1 , wherein the housing comprises a substantially cylindrically shaped portion having an opening extending therethrough, and wherein the opening defines a center axis. 
     
     
       3. The RFID device of  claim 2 , wherein the housing further comprises a flange portion, and wherein the flange portion includes the antenna. 
     
     
       4. The RFID device of  claim 1 , wherein the first casing of the housing includes a first side and a second side, and wherein the first side is adapted to be secured to the surface of the object by an adhesive. 
     
     
       5. The RFID device of  claim 4 , wherein the adhesive comprises Henkel Loctite4080 adhesive. 
     
     
       6. The RFID device of  claim 4 , wherein the first side of the lower casing includes a cavity configured to receive the adhesive to enable to the RFID device to be affixed to the surface of the object. 
     
     
       7. The RFID device of  claim 4 , wherein the adhesive has a greater adhesion strength than the strength of the first and second break-lines in the housing. 
     
     
       8. The RFID device of  claim 1 , wherein the first break-line is adapted to facilitate the breaking of adjoining or adjacent portions of the first casing along the first break-line in response to one or more forces, and wherein the second break-line is adapted to facilitate the breaking of the second casing of adjoining or adjacent portions of the second casing along the second break-line in response to the one or more forces. 
     
     
       9. The RFID device of  claim 1 , wherein the first break-line is defined in the top or bottom surface of the first casing or between the top and bottom of the first casing. 
     
     
       10. The RFID device of  claim 1 , wherein the second break-line is defined in the top or bottom surface of the second casing or between the top and bottom of the second casing. 
     
     
       11. The RFID device of  claim 1 , wherein the first break-line comprises one or more of the following: a recess, a groove, a notch, a cut, a hole or opening, a slit, a perforation, a scored or cut line, a line of weakness, a thinned area or line, a zigzag cut line, a radial wave line, or any combination thereof. 
     
     
       12. The RFID device of  claim 1 , wherein the second break-line comprises one or more of the following: a recess, a groove, a notch, a cut, a hole or opening, a slit, a perforation, a scored or cut line, a line of weakness, a thinned area or line, a zigzag cut line, a radial wave line, or any combination thereof. 
     
     
       13. The RFID device of  claim 1 , wherein the first break-line comprises a V-shaped cut. 
     
     
       14. The RFID device of  claim 1 , wherein the second break-line comprises a V-shaped cut. 
     
     
       15. The RFID device of  claim 1 , wherein the first break-line extends from the inner edge of the first casing to the outer edge of the first casing, and wherein the second break-line extends from the inner edge of the second casing to the outer edge of the second casing. 
     
     
       16. The RFID device of  claim 1 , wherein the first casing comprises a substantially cylindrically shaped portion having an opening extending therethrough, wherein the opening defines a center axis, and wherein the first break-line is oriented along a radial line passing through the center axis. 
     
     
       17. The RFID device of  claim 1 , wherein the second casing comprises a substantially cylindrically shaped portion having an opening extending there-through, wherein the opening defines a center axis, and wherein the second break-line is oriented along a radial line passing through the center axis. 
     
     
       18. The RFID device of  claim 1 , wherein the first break-line is aligned in a plane with the second break-line.
